A. J. BRIEGEL VENTILATING UNIT FOR STOVES Filed Jan. 21, 1952 INVENTORden. 24, 1933 UNITED STATES ANTHONY J. BRIEGEL, OF PITTSBURGH,PELl'NSYLVANIA VENTILATING UNIT FOR STOVES Application filed January21,1932. Serial No. 587,898.

'My invention relates to ventilators, and while primaril intended forstoves, it will be obvious that t e device may be successfully em loyedfor any other purposes wherein it is ound to be a plicable.

Important ob ects of the invention areto provide a ventilator of thecharacter described, which will efit'ectively remove and dissipatenoxious fumes, odors and vitiated air concomitant with the operation ofa cooking stove, and which may readily be installed to any type of stovealready constructed as well as form a component part of the stovestructure.

5 Further objects of the invention are to provide a device of the classstated, which is simple in its construction and arrangement, durable andeflicient in its use, compact, attractive in appearance, positive in itsaction, adjustable and comparatively inexpensive to manufacture,install, operate and maintain.

With the foregoing and other objects in view, which will appear as thedescription progresses, the inventlon consists of the novelconstruction, combination and arrangement of parts herein specificallydescribed and illustrated in the accompanying drawing, but it is to beunderstood that the latter is O merely illustrative of an embodiment ofthe invention, and that the actual needs of manufacture and practice maynecessitate certaln mechanical variations from the disclosure thereofherein illustrated It is therefore, not

5 intended to limit the invention to the embodiment thereof disclosed inthe drawing, but rather to define such limitations in the scope of theclaim hereunto appended.

In the drawing wherein like numerals of 0 reference designatecorresponding parts throughout the several views Figure 1 is afragmentary side view of a stove, provided with a ventilator, shown incross section and constructedin accordance 45 with the invention.

Referring in detail to the drawing, 1 de-' 0 notes a cooking stove whichmay be of any type and construction, and employ gas, coal or any otherfuel. a

My improved ventilator is positioned above and spaced from the top 2 ofthe stove 1, and carriedby a suitable support 3, which is preferablymounted at the rear of the stove 1.

The ventilator comprising a hollow body portion 4, which is divided by ahorizontally extending partition wall 5 to provide a lower passagechamber 6 and an upper fan chamber 7. A fan 8 is mounted in the fanchamber 7 and operated by an electric motor 9. The latter is supportedon the top of the body portion 4 and suitably joined with the fan 8 tooperate the latter within the fan chamber 8.

A passage opening 10 is formed in the partition wall 5 to establishcommunication between the passage chamber 6 and the fan chamber 7. Alongitudinally extending inlet passage slot 11 is formed in the bottom12 of the passage chamber 6. The passage slot 11 is preferably disposedadjacent to the front of the body portion 4 and extends throughout thelength of the latter.

An adjusting plate 13 is shiftably mounted against the under side of thebottom 12, and has its ends respectively engaged in a pair of guides 14fixed to the bottom 12. The plate 13 is provided with a depending lip 15having a threaded aperture for the engagement of an adjusting screw 16.The latter extends through an aperture provided in a depending lip 17carried at the front of the bottom 12. The plate 13 extends parallel tothe bottom slot 11 and the adjustment of the screw 16 will shift theplate 13 forwardly or rearwardly to provide a passage slot area to bestmeet conditions found in practice. An outlet passage neck 18 is formedat the rear of the fan chamber 7 for connecting a flue or stove pipe 19therewith. The latter communicates with the chimney in the usual manner.

During the operation of the ventilator, all fumes and vitiated airemanating from the stove 1 will be drawn upwardly through the slot 11into the passage chamber 6, through the opening 10 into the fan chamber8, and then removed through the neck 17 and flue ipe 18, as clearlyindicated by arrows in i ure 1.

. he present invention provides a most efficient device of its kind,which will function effectively to remove and dissipate fumes,-

odors and vitiated air from the vicinity of its location, and which maybe so cheaply constructed and operated as to render same available forhome use as well as in institutions and the like.

What I claim is In combination, a stove ventilator comrising a hollowbody portion, a horizontaly extending partition wall in said bodyportion and dividing the interior of the latter into a passage chamberand a fan chamber, a suction fan mounted in said fan chamber, a motorfor driving said fan and mounted on the top of said body portion, saidparti- .tion wall having a passage opening disposed directly beneathsaid fan, the bottom of said passage chamber having an air inlet slot atthe front thereof, a pair of guides carried by said bottom and disposedat respective ends of said air inlet slot, a plate shiftably mounted insaid pair of guides and provided with a depending lip, a depending lipcarried by said body portion, and an adjusting screw engaging saiddepending lips and operable for shifting said plate to regulate said airinlet passage, substantially as described and for the purpose set forth.

ANTHONY J. BRIEGEL.
